Abstract (en)
[origin: WO2016119543A1] Phase control apparatus and methods for antenna arrays are disclosed. Phase shifting for antenna beam steering or beamforming is broken into a fixed phase shift stage and a variable phase shift stage. The fixed phase shift stage includes one or more fixed phase shift elements with fixed phase shifts. The fixed phase shift stage provides coarse phase control. The variable phase shift stage provides fine phase control with a resolution or granularity that is finer than the fixed phase shifts of the fixed phase shift elements. Amplitude control could also be provided for beam steering, to compensate for amplitude effects of the phase shifting, or both.
